Help compiling TCL 8.0.3 with GCC-2.95.2 Upgrade

[Allan S Iverson]

I am trying to compile TCL 8.0.4 using Cygwin 
b20 with GCC-2.95.2 downloaded from www.xraylith.wisc.edu/~khan/software/gnu-win32/ .
 
I also downloaded a patch Tcl 8.0.4 diffs from 
Mumit Khan at the same site and applied it.  I also had earlier 
downloaded and installed Munit's binary build for Tcl/Tk 8.0.4, Tix, and BLT 
2.4g for Cygwin b20 from the same web page. However I now need a complete 
source tree for another project that depends on being able to access the 
tclusing more then just tclConfig.sh.   I then attempted to build 
tcl8.0.4 from the patched sources. Note: Complied with -U_WIN32 added to 
Makefile after running configure I think this is necessary otherwise 
generic/tclPort.h includes  "../win/tclWinPort.h" instead of 
"../unix/tclUnixPort.h"
 
I received the following warnings and 
errors. The library appeared to build but is unusable because of the many 
undefined references. 
 
Been working on this with only a couple hours 
sleep in the last two days and could use some suggestions.
 
Hope somebody can help.  TIA Allan
